Specification of Letters Patent.

Patented Mar. 5, 1918.

Application med August 11, 1916. Serial No. 114,428.

To all whom it may concern:

Be it known that I, JOHN G. Rmnnn, a' citizen of the United States, residing at Roseville, in the county of Placer and State of California, have invented certain new. and useful Improvements in Ventilators, of which the following is a specification.

This invention relates,to ventilators, and more particularly to a ventilator adapted to be used in conire ction with a window of ordinary construction.

One'of the main objects of the invention is to provide a ventilator of simple construction adapted to be attached to a window sash so as to be movable therewith. -A further object is to provide'a ventilator which can be quickly and easily adjusted to suit special conditions. Further objects will appear from the detailed description.

In the drawings:-

Figure 1 is 'a front view of the invention 7 lig. 2 is a section on line 22 of Fig. 1, an a Fig. 3 is a detail.

Broadly stated, my invention comprises a ventilator frame adapted to be securedto the lower sash of a window and a deflector rockably mounted in the ventilator frame and adjustable so as to vary its inclination as required. The ventilator frameconsists of two tapered V-shaped end pieces 1 and 2 connected at their upper ends by a top frame 3, the inner side of which is secured to the top bar 4 of the lower sash 5-of the window. This top frame 3 supports a screen 6 of suitable wire, and a. similar screen 7 is secured over the front of. the ventilator frame by means of strips 8 and 8 secured to the inner edges of the end pieces 1 and 2, respectively. This forms a downwardly tapering V-shaped.frame, the top and front of which are completely closed by screening wire so as to efiectually prevent theentry of flies and similar insects into the room.

The outer edges of the end pieces 1 and 2 are firmly secured to the inner faces of the side bars 9 of the lower sash 5. This sash is connected by the usual cords 10 to weights, not shown, in boxings at the sides of the window casings, so as to be readily adjustable between the usual strips 11.- A top sash 12 is similarly mounted in the window casing and coiiperates with the lower sash to entirely close the window opening, in the usual manner. By this means the ventilator frame may be readily 'moved into either an upper or a lower position in the window casing, as desired.

A tapered block 13 is fixedly secured at the apex of the ventilator frame. This block ex-- tends the full width of the frame and is provided, on its upper edge, with a bead 14 and an outwardly adjacent the ad. This block is further provided with a channel 16 adjacent the inner face of the bead and an upwardly'and inwardly tapering projection 17 A supplemental sash 18 is mounted in the ventilator frame. This sash is provided, in its lower bar. 19 with a groove extending 1ongitudinally thereof and' adapted to fit snugly on Egojecting shoulder 15 closely the head 14. This sash is of'such a height 3 that the top bar 20 thereof fits tightly agamst the inner face of the top bar 4, of

- the window sash 5,-when sash 18 1s in a vertical position, and the lower-edge thereof is in the same horizontal plane as the lower edge of the bar 4. The. sash 18 is also of a Width such that its end bars18 are'in alinement with the end bars'of the'sash 5. The

usual pane of glass is omitted from the win- .dow sash and sash 18 is provided with a pane of glass 21. By this arrangement, when the supplemental sash is in a vertical position, the opening through'lower sash 5 will be completely closed while permit ting ready access of light to the room.

An arcuate bar 22 is secured to thetop arm of a U-strap 22 extending across the top screen frame and secured to the 'inner and outer bars thereof. This bar has one edge provided with a pluralityv of serrations 22. A tension coil spring 23 is'secured at its lower end to the center of the top bar 20 of the ventilator sash 18 and has its upper end secured to a button 24. The spring 23 extends through a slotformed in the top screen 6 in vertical alinement with the serrations of the bar 22. By raising the button 24 and shifting the same along the bar the ventilator sash is rocked about its pivotal axis so as to vary its inclination according to circumstances.

frame may be secured to the bottom bar 4 of the lower sash 5, if desired. This provides anadditional means for securmg the The block 13 at the apex of the ventilatorend of the same.

When the ventilator sash is in opened 0- sltion it is inclined upwardly and inwar y so that the air flows into the room through the screen 6, taking an upward direction. If desired, the sash 5 may be raised to the upper end of the window casing so that the air will enter at the top of the window instead of atan intermediate oint. By this means the ventilator can be a justed so as to suit particular requirements.

The tension spring 23, in addition to serving as means for adjusting the deflector or ventilator sash, also serves to permit limited movement of the sash. This feature is of importance in connection with sudden gusts of wind which would exert undue pressure upon the pane 21 of the sash which would, in some cases, be sufficient to break the same. In the case of a sudden gust of wind striking the pane 21, the tension spring will permit limited inward movement of the deflector thus permitting a greater amount of am to enter the room through the screen 6 than normal andin this manner relieving the pressure on the pane so as to prevent breakage of the same. When the pressure is removed from the pane the spring will act to return the deflector to the position at which it was originally adjusted.

It will be obvious that certain changes may be made in the constructionand arrangement of the different parts of my invention without departing from the field and scope of the same, and I intend to include all such variations in this application, as fall within the scope of' the appended claims, in which a preferred form only of my invention is disclosed. L

What I claim, is

1. In a ventilator of the class described, the combination of a frame, a sash rockably said messes mounted at its lower end in the frame, a serrated bar carried by the frame, a'button ad ustable longitudinally of the bar, and resilient connections between the button and the sash whereby the inclination of the latter may be varied, so as to permit adjustment thereof, said resilient connection serving to normally-maintain the sash in' adjustment while permitting movement of the sash in either direction under the impulse of strong drafts or wind.

' 2. In a ventilator, a frame, a sashrockably mounted at its lower end in the frame,

a serrated bar secured across the top of the frame, a button adjustable longitudinally of said bar, and a tension sp secured to the button and to the top of the sash, said spring being engageable with the teeth of said bar so as to secure the button in adjustment longitudinally thereof, the spring providing a resilient connectlon between the frame or sash whereby the sash is 'normally held in adjusted position but may be rocked in either direction under the impulse of strong drafts or wind.

3. In a ventilator a frame, a. sash rockably mounted at its lower end in the frame,

an arcuate bar secured across the top of the frame at right angles to said sash and having one ed e serrated, a button adjustable longitudinally of the bar, and a tension spring having its lower' end secured to the top bar of the sash and, its upper end secured to the button, the spring being provided at its upper end with a straight portion {)or engagement with the serrations of In testimony whereof I aflix my signature in presence of two witnesses.
